What are examples or centripetal acceleration?

Answers

Answer 1

Answer: Centripetal acceleration is necessary, and is present, whenever any object
moves in a closed path, or along any part of a circular path. Some examples
I can think of are:

-- a planet or a comet in orbit around the sun
-- a moon in orbit around a planet
-- the little ball making circles around the spinning roulette wheel
-- a stone tied to the end of a string, when you spin it around your head
-- the end of the spinning string on a weed-whacker
-- the tip of the blade of a fan or a windmill
-- any little bit of rubber on a car tire or bicycle tire, when they're moving
-- a strawberry seed spinning around the inside of the blender jar when you're
making a smoothie
-- a car driving around a curve in the road
-- you on almost any amusement park ride; whenever you're not moving in a
straight line, you're experiencing centripetal acceleration.

Answer 2

Answer: centripedal acceleration :

⇒ the moon in orbit around a planet (or the sun).
⇒ The Earth (or an other planet) in orbit around the sun.

For a conclusion to be accepted by the scientific community, the data must be accurate, free from error, andA.reproducible.

B.varied.

C.unique.

D.surprising

Answers

The data must be reproducible: it means that the data will be reliable and representative and not that this data would lead to one conclusion and another data would lead to another.

Data being varied, unique or surprising does not have anything to do with acceptability of the conclusion.

I need help I can't solve it and I'm struggling badly. Justin weighs 185 lb. and decides to climb a staircase that has a vertical distance of 12 m. He climbs the stairs in 12.7 seconds. Calculate his work:

Answers

Answer:

Power is work/time - not needed here

W(work) = F * D force * distance

Here W = M g h

Since 2.20 lb is equivalent to 1 kilogram mass

W = 185 lb / 2.20 lb/kg * 9.80 m/s^2 * 12 m = 824 Joules

note that a pound is a unit of force and a kilogram is a unit of mass

A cylindrical water tank has a radius of 3 yards in the 7.5 yards high what is the volume of the tank

Answers

To calculate the volume of a cylindrical water tank, you can use the formula for the volume of a cylinder:

Volume = π * r^2 * h

Where:

- π (pi) is approximately 3.14159

- r is the radius of the cylinder

- h is the height of the cylinder

In this case, the radius (r) is 3 yards, and the height (h) is 7.5 yards. Plug these values into the formula:

Volume = π * (3 yards)^2 * 7.5 yards

Volume ≈ 3.14159 * (9 square yards) * 7.5 yards

Now, calculate the volume:

Volume ≈ 3.14159 * 67.5 cubic yards

Volume ≈ 212.05325 cubic yards

So, the volume of the cylindrical water tank is approximately 212.05 cubic yards.
